Matau's Toa Metru Mini Promo CD

This mini CD-ROM is based on the early 2004 storyline of LEGO BIONICLE. In this adventure, the player takes control of Toa Metru Matau, who is journeying through Le-Metru on Metru Nui. He is trying to find the Le-Matoran Ussal Rider Orkahm, who can help him find the Le-Metru Great Disk, which is needed to defeat the Morbuzakh, a giant, intelligent, evil plant whose vines are appearing all over the island city, causing massive destruction. Along the way, the player will encounter other Matoran, who will provide Matau information, and puzzles, which must be solved to find clues as to Orkahm's whereabouts.

The game plays in a linear, storybook-like fashion, where once all tasks in an area have been completed, the player moves on to the next. Arrows at the bottom of the screen let the player move on once they are done in an area, or backtrack to previous areas. There are hot spots the player can click on. These include characters the player can talk to, puzzles the player needs to solve, and also random objects that, when clicked, give the player trivia about Metru Nui.

The mini CD-ROM was originally released with the LEGO BIONICLE canister set 8605 Toa Matau, but this release was exclusive to European countries. The executable setup file was later made available for download on BIONICLE.com's Kanoka Club worldwide.
